Abstract

A method for producing a display comprising a carrier substrate made of glass, the display having flexible, bendable and/or elastic properties in a predetermined region of the carrier substrate, includes introducing modifications into the carrier substrate within the region by laser radiation along a closed and/or linear contour and/or points. Within the region, a one flexible, bendable and/or elastic layer is applied. A side of the carrier substrate facing away from the layer is subjected to an etching attack, by which material removal from the carrier substrate takes place along the modifications along the contour and/or at the points of the region until recesses are produced that extend across or over a substantial part of a material thickness of the carrier substrate.
